I recently removed a 20 year old vented space heater replacing it with a new vent free unit. I'm happy with the fact the new unit heats more space at less cost. However I now find more moisture showing up on windows and doors . Items stored in unisulated closet space is now collecting moisture and mold. The co detectors are not going off. So I have not looked for vent problems. Would tighting up the exterior stom windows and replaceing the exterior doors with newer insulated unit correct my problem?

Tightening up the envelope reduces heat loss but it will only increase your condensation woes. When you replaced the vented with the non vented space heater you eliminated a means for humidity to escape. Talk to your local HVAC rep about a HRV(HEAT RECOVERY VENTILATION) system. It will bring in fresh air heated by the warm moist air it is expelling. This will aid the condensation problems and improve the interior air quality.
